STOP AND WASTE VALVE.

Specification of Letters Patent.

Patented Jen. 19, 1909.

Application tiled July 30, 1907` Serial No. 386,177.

To all whom it may concern:

lle it known that I, DENNIS C. CHARMOIS, a citizen ot' the UnitedStates, residing at Canton, in the county of Stark and State of Ohio,have invented a new and useful Stop corresponding guide ribs 13 formedin the case, so that the valve-block is held agamst rotationin itsendwise movements. The apertures 14 are provided in the lower part ofthe sides of the block, through which aperand faste Valve, of which thefollowing is i tures the water can flow from the case-chamaspecification.

The invention relates to a valve adapted to stop the flow of water orother liquids and fluids in a pipe, and the object of the invention isto permit a free and ready waste of the liquid which has passed throughthe valve, after the same has been closed. 'ihis object is attained byproviding a wastevalve in addition to the ordinary stop-valve, and toarrange the same so that the wastevalve is automatically opened atsubstantially the same time the stop-valve is seated, and conversely,.so thaty the waste-valve is closed at substantially the same time theopening ot' the stop-valve is begun.

-i preferred form for embodying the invention is illustrated in theaccompanying drawings, in which# l r i i Figure 1 is a longitudinalsection showing the waste-valve as applied to an ordinary globevalve;Fig. 2, a transverse sccton of the same; Fig. 3, a cross section on line8 3, Fig. 2; Fig. 4, a detached longitudinal sectionfof the valve-block;Fig. 5, a

detached perspective view of the same; Fig.l

low valve-block 6, having the stop-valve 7 formed or attached on Aitsinner end, the tubular main-stem S having a screw engagement through theouter end of the block, andthe waste-valve 9 located in the cavity 10 ofthe block and having its guide-stem 11 entered in the bore ofl theniainestem.

The valve-block 6 is preferably cylindric in form and is adapted tooperate endwise in the valve-chamber 5. ,The longitudinal grooves 12 areprovided in the sides of the valve-block which are adapted to'yre'ceivethe l her 15 into the cavity 10 of the valve-block.

As illustrated, these apertures arerin the form of slotsr oaeningthrough the bottom of the lower en oi the guide-grooves. but thisparticular form and location of theaperturesisnot essential.

The main-stein 8 is provided with the annular flange 16 engaging whichare pro# vided suitable packing rings and disks, as 17 and 1T. thuspermitting. a free rotation butl preventing an endwise movement of themain-stem. The coarse thread 18 on the inner cnd ot the main-stein is'adapted to operate. in the conversely threaded aperture 19 in the outerend of the valve-block, whereby the rotation of the stem one way or theother will move the block inward or Out- The waste-valve 9 is adapted tobe seated against the innerrend 10 ot' the main-stem when the same hasbeen turned into the cavity'lO of the block, as shown in Fi 2, and theshoulder 2O is formed in the bick,

which shoulder is adapted to stop and un# tioned that the last turnofthe mam-stemfor seating the stop-valve will serve to unseat thewaste-valve. The apertures 23 and 23 are provided in the sides of themainstem and the bonnet-cover respectively, which apertures registerwith the annularr port 24 formed in the cover and permit a free exit ofwater from the, bore 'of the main-stem. 4

In. the use ofthe Valve, when the stopvalve is opened, as shown in Fig.2, the waste-valve is firmly 'seated against the inner end of themain-stem by the pressure of the water in the cavity of'the block, thusreventing an flow of Water throughthe ore of the main-stem. When thestop-valve is being closed by rotation of the mainl last turn of themainstem which serves to E v place when th operating `beyond thestopshoulders'7 so that the Waste- Vthe water; and if the valve hasdropped -its seat by the suction of the Water flowing stein and theconsequent inward movenzent 'l of the valve-block, the stop-shoulder 20in i the block unseats the Waste-valve during the l seat'the stop-valve,as shown in Fig. 1, and in this relation of the parts the `vWater isfree' to Waste from the case-chamber 14 beyond the stop-valve. `When theWater has wasted from this chamber the Waste-valve is free to dropdownward to the Aposition shown by broken lines in the same figure in ivevent the operating parts are located on the upper side of the case, asillustrated;- but this movement of the Waste-valve is notnecessary oressential and does not take 4 parts are located on the under side of thecase. Then the stop-valve is opened, the first turn of theI main-stemWill cause its inner end to protrude inWardint-o the cavity of the blockvalve is seated thereon by the pressure of downward to the positionshown by broken lines in Fig. 1, it is promptly raised against aroundit.

The projection 11%' which as shown may bethe head of the guidestemscrew, is pret'- erably provided on the lower side of the| Waste valveto hold the body of the Waste-r' valve away from the bottom ot' thevalveblock, and the diameter ofthe Waste-valve is proportioned to thecavity of the valve` bloc-k, so that the suction of Water passingoutward through the cavity will surely close the Waste-valve against theend of the m ainstem.
